As the name of this LSA implies, its transmission scope is defined as being confined to a local network or subnet only.
NOTE Opaque LSAs are used for Multiprotocol Label Switching (MPLS) traffic engineering purposes. Specifically, opaque LSAs are used to distribute various MPLS traffic engineering attributes, such as capacity and topology of links, throughout a network. In addition to Cisco, other major vendors such as Juniper and Riverstone implement opaque LSAs; however, as indicated in RFC 2370, "The OSPF Opaque LSA Option," determining their use is vendor-specific. Therefore, some testing might be required to find the optimal use of opaque LSAs across different platforms.
